IMPROVEMENT IN CAR-AXLE BOXES.

Specification forming part of Letters Patent No. 158,358, dated January5, 1875; application led August 17, 1874.'

To all whom it may concern:

Beit known that I, TnoMAs H. BURRIDGE,

of St. Louis, St. Louis county, Missouri, have,

invented a certain new and useful Improvement in Oilers for Oar-Axles,of which the following is a specification:

This is an improvement and simplification of my device for oilingrailway-car axles, for which Letters Patent of the United States weregranted t0 me on the 2d day of June, 1874, and numbered 151,562.

My patented device consists of a single pad and counter-balance, mountedon a shaft below the axlejournal, and oscillated by means of suitablegearing connecting it with the axle, so as to periodically immerse saidpad in the lubricant in the bottoln of the oilbox.

In the present device I dispense with `the gearing mechanism, and addfeatures which are new in construction and operation.

This improvement consists in a rocking frame, supported in the oil-boxbeneath the axle, and carrying' at the ends pads, which, as the box isshaken, (by the movement of the car,) are thrown up alternately againstthe underside of t-he axle-journal. Depending from these pads are beardsof cotton wicking or other brous material, to supply oil to the pads bycapillary attraction. When the oil is low in the box these beards stillcarry up a sufficient quantity of oil to lubricate the journal. To eachpad is attached au ear, having an eye, into which may be hooked aweight, to counterbalance any redundancy of weight in the other pad, andwhich would otherwise interfere with the regular rocking of the frame.

In the drawings, Figure l is au end view of the axle and oiling devicewithin the oilbox. Fig. 2 is a top view of the oiler, showing partsbroken away to exhibit construction. Fig. 3 is a side elevation of theaxlejournal and oiler in position in the oil-box, which latter and thejournal-box are in section.

A is the oil-box. B is the journal-box. C is the axle, and D theaxlejournal. The oiler-frame has an arm, E, secured by a bolt, screw, orrivet, F, to the side of the oil-box.

To the arm E is attached a plate, G, lying on the bottom of the oil-box,and supporting two uprights, H I. K is a rock-shaft, with bearings inthe tops of the uprights H I. The shaft K is preferably made removableby the following` means-one end is first inserted endwise into theupright I, and the other end is then dropped into the open-toppedbearing in the top of the upright H, and is held down by a hook, L. M Mare arms, extending from opposite sides of the rocksbaft, and carryingat their ends cross-arms N N, upon which are secured the perforatedpad-plates O O.

The arms M M pass through the crossarms NN, but the joint is preferablymade so loosely thatthe cross-arms have freedom to turn upon the arms MM a limited distance to either side, to accommodate the surface of thepad to the journal' in cases where the oil-box is not straight with thejournal, or the oiler is not in proper relative position with thejournal, from any cause.

Through the perforations in the plates O O pass cotton wicking orstrings of other fibrous material, P, whose ends or loops p hang down tothe bottom of the oil-box, so as to take up oil by capillary attraction,and cause the saturation of the part of the material above the plate,and which forms the lubricating surface of the pad. The upward flow ofoil in the hanging ends p is aided by the ilexure of the ends caused bythe rocking of the shaft K.

The lower ends of the cross-arms N N extend downward, and form-ears n a,which are perforated to receive the suspension-hooks of a weight, It,whose office is to counterbalance any inequality in weight between thetwo pads, and to thus overcome the tendency of either pad to remain inconstant contact with the journal. The weight is of course suspendedfrom the lighter pad, so as to give it an equal weight with the other.

The arrangement is such that the shaking of the oil-box, when the carsare in inotion, will oscillate the pad-frame, so as to bring the padsalternately in contact with the journal.
